==Explanation==
Several of these series have been released in a series of five consecutively released comics using all five regular days in a week (like for instance with [[:Category:Secretary|Secretary]]). This occurred several times between 2006 and 2010. But since then no series were released like this, although some series were released but with long separation between releases. That was until October 2016, when the "strange" series [[:Category:Time traveling Sphere|Time traveling Sphere]] were released. In the explanation for that series the strangeness of its release is discussed, relating back to how other series mentioned here have been released.

===True series===
*Here is a chronological list of all (29 as of July 2021) true series (removing those made for explaining certain aspects of xkcd without being a series in any clear way on xkcd). 
**A series first becomes a series when it is clear that it will be a series, i.e. usually when the second comic in the series is released. It is thus not the first comic that determines the date for a series, but the second. 
**The list here below is sorted after that date, when the second comic where released.
#[[:Category:Barrel|Barrel]]
##A five (or six) comic series released over one and a half month from September 2005. The very first comic on xkcd was named [[1: Barrel - Part 1]] showing that there were more than one in the series, and the next four parts (as well as [[20: Ferret]] belonging to the series) where released within 2 months of each other. The normal schedule was not in place at that time, and the first two parts where [[:Category:First day on LiveJournal|released on the same day]] on [[LiveJournal]], and they were not released in the order they are shown on [[xkcd]] today, as the order of comics where changed from [[:Category:Posted on LiveJournal|that on LiveJournal]] when xkcd.com went live in 2006. So originally Barrel was not the first comic to be released.
#[[:Category:Red Spiders|Red Spiders]] 
##A four (or five to seven) comic series released over more than half a year from September 2005 to June 2006. The first comic was [[8: Red spiders]], released on the first day (as with Barrel above), but it first became a series when [[43: Red Spiders 2]] was released two month later with the same title and a number. A month later [[47: Counter-Red Spiders]] came out. The last true comic in the series was [[126: Red Spiders Cometh]] released half a year later. Only those four uses "Red Spiders" in the title. But later Red Spiders where depicted again (as in [[427: Bad Timing]]), but those were call backs to the original series rather than as a true part of the series.
#[[:Category:Opening dialogue by Scott|Opening dialogue by Scott]]
##A three comic series released consecutive over the last part of a week. They were released the first week after xkcd comics where no longer released on LiveJournal but only released on xkcd. The first was released on January 31st 2006. The first comic released that week and only on xkcd was not part of this series. So when [[Randall]] wished to have all these three with the same title text (''Opening dialogue by Scott'') in the same week, the first [[57: Wait For Me]] was released already on the Tuesday after the Monday release. This was the first time a series had been released consecutively in a week. But the three comics where not directly related.
#[[:Category:Parody Week|Parody Week]]
##A five comic series released over five consecutive days from Monday-Friday in August 2006. It was the first time of six that this occurred. The theme was the same, parodying other web comics, but there were no connection between the comics themselves.
#[[:Category:Choices|Choices]]
##A five comic series released over five consecutive days from Monday-Friday in May 2007. It was the second series released like this, but it was the first time of four that the five comics of such a series were directly connected in a continuation story line. 
#[[:Category:1337|1337]] 
##A five comic series released over five consecutive days from Monday-Friday in November 2007. It was the second series released like this where the five comics were directly connected in a continuation story line. 
#[[:Category:Journal|Journal]]
##A five comic series released over about five month the first [[374: Journal]] in January 2008. It first became a series when the second comic [[377: Journal 2]] was released a week later at the end of January with a “2” to indicate that this was a series. Each of the first four comic was released in different weeks, the third first in April and the fourth in June. But the last comic [[433: Journal 5]] was released the next release day (Friday) after [[432: Journal 4]]. This is the only series that behaves like this. Apart from that it behaves like the other five comics in one week series, with a number indicating it is a series. This thus makes it the fifth comic with five comics that are directly and chronologically ordered. (The Barrel series is in some way similar, but cannot really be considered as being the same type as this and the other four consecutive comics).
# [[:Category:Secretary|Secretary]]
##A five comic series released over five consecutive days from Monday-Friday at the end of October 2008. It was the third series released like this where the five comics were directly connected in a continuation story line. 
# [[:Category:Well|Well]]
##A two comic series released with about two weeks between them. When the first comic [[561: Well]] was released in March 2009 it was not a series. That was first obvious when [[568: Well 2]] was released in April. It is the first time that Randall made a two comic series like this by adding a 2 after the title of a previous comic. But this happened several times later, but then not always with a continuing storyline as in Well. Of course the numbering like this was also used for Journal and Red Spiders, but both of these had more comics in their series.
#[[:Category:The Race|The Race]]
##A five comic series released over five consecutive days from Monday-Friday at the beginning of May 2009. It was the fourth and last series released like this (as of 2016) where the five comics were directly connected in a continuation story line. But one more series were released like this the year after, but those comics stories where not related.
#[[:Category:Android|Android]]
##A two comic series released with less than two weeks between them. When the first comic [[595: Android Girlfriend]] was released in June 2009 it was not a series. That was first obvious when [[600: Android Boyfriend]] was released later that month. It was the first series where it was only part of the title that made it clear it was a series. And no numbering was used. The plot though also makes the connection clear. A similar connection between comics in series was not seen before ''Time traveling Sphere'' seven years later (see below).
#[[:Category:Online Communities|Online Communities]]
##A two comic series released with more than three years between the first [[256: Online Communities]] in May 2007, and the second [[802: Online Communities 2]] from October 2010. It was first the latter that with the same title and a number 2 made it into a series. This is the reason it is first listed chronologically here. It was not a series in 2007. Adding the number “2” to make it into a series is like the Well series, and this was the second time that happened.
#[[:Category:Five-minute comics|Five-minute comics]]
##A three comic series released consecutively over a week using the normal release schedule in the middle of November 2010. This is the second time a series has been released with three in one week, following the Opening dialogue by Scott in 2006 (but that time there were four comics in the week, one not belonging to the series). It is thus the only time that a week with three comics only where all released as a series. It was the first of two weeks in a row with series. Both series were made to give Randall some time to cope with his wife’s cancer.
#[[:Category:Guest Week|Guest Week]]
##A five comic series released over five consecutive days from Monday-Friday at the end of November 2010. It is so far (as of 2016) the last time of six that this occurred. The theme was the same, with five web comic artist making guest appearances on xkcd, so there were no connections between the comics themselves. It is the second time this happened, the first time was the first five day series in August 2006. It was the second of two weeks in a row with series. Both series were made to give Randall some time to cope with his wife’s cancer. Since this comic there has never been released more than three comics in a week. Also until October 2016 with the ''Time traveling Sphere'' there were never to comics directly related which were released in the same week (see below).
#[[:Category:Etymology-Man|Etymology-Man]]
##A two comic series released with during one weeks with one comic in between. When the first comic [[1010: Etymology-Man]] was released on Monday January 30th 2012 it was not a series. That was first obvious when [[1012: Wrong Superhero]] was released Friday of the same week. There is no storyline connection between the two, but Etymology-Man from the first is the wrong superhero in the next.
#[[:Category:xkcd Phones|xkcd Phones]]
##An eight comic series (as of October 2020) released over six years between the first [[1363: xkcd Phone]] in May 2014 and the latest [[2377: xkcd Phone 12]], from October 2020. It was first with the release of the second [[1465: xkcd Phone 2]] in December 2014 with the same title and a number 2 that it became a series. Adding a number to a title has been used like this two times before, but it is the first of this kind of series to progress beyond 2, so far all the way to 6. Only in Journal (that went to 5) did the numbering without including "part" progress beyond 2, and that was a true series where the story was connected. This is also what makes this a special type of series in xkcd not seen before, as it is clear that these are a series, but they are not connected as a story. After number six the number that did not just go one up (2-6 for the second to sixth), but used 2000 to coincide with it being comic 2000 on xkcd. But then the next, number eight used the number 12 as it was released near the relase of {{w|iPhone 12}}.
#[[:Category:Exoplanet Names|Exoplanet Names]]
##A two comic series released with almost a year between the first [[1253: Exoplanet Names]] in August 2013, and the second [[1555: Exoplanet Names 2]] from July 2014. It was first the latter that with the same title and a number 2 made it into a series. This is the reason it is first listed chronologically here. It was not a series in 2013. Adding the number “2” to make it into a series is like the Well series, and this was the fourth time that happened and so far (as of 2016) the last time. These two comics are not connected as a story, rather the second is an update to the list made in the first, even including most of the first list. In that was this is a special type of series, in someway related to the xkcd phone series above. The first of these two comics came out before the first phone comic, but the second phone comic came before the second of these, thus explaining the chronology.
#[[:Category:Synonym Movies|Synonym Movies]]
##A two comic series released with less than two weeks between them. When the first comic [[1563: Synonym Movies]] was released in August 2015 it was not a series. That was first obvious when [[1568: Synonym Movies 2]] was released later that month. There is no storyline connection between the two, but the idea is the same, showing DVD boxes with real movie titles changed using synonyms.
#[[:Category:Substitution series|Substitution series]]
##A three comic series (as of 2016) released over almost three years between the first [[1288: Substitutions]] in November 2013 to the third [[1679: Substitutions 3]] from May 2016, It first became a series with the second comic [[1625: Substitutions 2]] released in January 2016, explaining why it is placed after the two above. It is not a continuing series, but rather the same concept used again, more related to the xkcd Phone or Exoplanet names above, than to a comic series like Well. It was for long the only series, with numbers added, released like this over long time, that was at only three releases. But in February 2020 the [[:Category:Stargazing|Stargazing]] series also got a third installment.
# [[:Category:Code Quality|Code Quality]]
##A five comic series (so far as of April 2019) released with exactly four years years between the first and so far last in the series. When the first comic [[1513: Code Quality]] was released on the 17th of April 2015 it was not a series. That was first obvious when [[1695: Code Quality 2]] was released in June 2016. This series reminds of Well and Android, but with much longer time between the two releases. And then it continued with [[1833: Code Quality 3]] in May 2017 still adding to the number. It then changed the naming in [[1926: Bad Code]], which clearly belonged to the other three. This was released in December 2017. And has so far the series ended with yet another comic that changed the name again, this time to [[2138: Wanna See the Code?]] released on the 17th of April 2019, on the four year anniversary of the first in the series.
#[[:Category:Time traveling Sphere|Time traveling Sphere]]
##A two comic series released over two consecutive but normal release day in the same week (a Monday and a Wednesday) in the middle of October 2016. This was a very strange release in many ways, and that has been described in great detail in the series category. It was first clear that this was a series with the Wednesday release [[1748: Future Archaeology]] but not from the title which has very little direct relation to the first title [[1747: Spider Paleontology]], but the plot was clearly a continuation of the first comic. The series could in principle continue later, but it did not fill out the entire week, and stopped at those two.
#[[:Category:Bad Map Projections|Bad Map Projections]]
##So far four comics have been released over more than four years, but given the Map projectons have numbers 79, 108, 299 and 358 there could be many more to come.
##The first was released on January 11th 2017, it was <nowiki>#107</nowiki>: [[1784: Bad Map Projection: Liquid Resize]]. And it became a series with the second comic released just a little more than a month later on February 15th with <nowiki>#79</nowiki>: [[1799: Bad Map Projection: Time Zones]]. The third, came almost three years later, and had <nowiki>#358</nowiki>: [[2256: Bad Map Projection: South America]]. It was released in January 2020. And one and a half year later the fourth <nowiki>#299</nowiki> [[2489: Bad Map Projection: The Greenland Special]] came out in July 2021.
#[[:Category:ISS Solar Transit|ISS Solar Transit]]
##Two comics was released Monday and Friday in the same week. Just at with the ''Time Traveling Sphere'' mentioned above, this was yet a new way to release a series.
##The first comic, [[1828: ISS Solar Transit]], was released on April 24, 2017 and the second, [[1830: ISS Solar Transit 2]], four days later on April 28, 2017. Once again a series where the second comic just adds a "2" to the title.
#[[:Category:X Years|X Years]]
##A three comic series (as of 2020) released over eight years between the first [[1141: Two Years]] from November 2012 to the third [[2386: Ten Years]] from November 2020. 
##It first became a series with the second comic [[1928: Seven Years]] released in December 2017, five years later, duh! This is the date that is used to arrange it in this list. 
##The series is about how many years it has been since Randall's wife's cancer diagnosis.  
#[[:Category:Stargazing|Stargazing]]
##A three comic series (as of 2020) released over just a bit more than four years between the first [[1644: Stargazing]] in February 2017 to the third [[2274: Stargazing 3]] from February 2020. 
##It first became a series with the second comic [[2017: Stargazing 2]] released in July 2018, one and a half year after the fist, explaining why it is placed after the three above. It is now the second series so far released like this, with numbers added,  over long time that is at three releases, the first being the [[:Category:Substitution series|Substitution series]].
##Once again a series where the follow up comics just adds a number to the title.
#[[:Category:Horror Movies|Horror Movies]]
##A two comic series released with six and a half weeks between them. When the first comic [[2056: Horror Movies]] was released in October 2018 it was not a series. That was first obvious when [[2076: Horror Movies 2]] was released towards the end of November 2018. The second comic continues the discussion of "why horror movies exists" directly from the first comic.
##The first comic was released on October 8, 2018 and the second, on November 23, 2018. Once again a series where the second comic just adds a "2" to the title.
#[[:Category:Coronavirus Genome|Coronavirus Genome]]
##A two comic series released over two consecutive but normal release day Friday and Monday (a first that it went over two weeks but still consecutive). The first comic [[2298: Coronavirus Genome]] was released at the end of April 2020. 
##It was first clear that this was going to be a series with the Monday release [[2299: Coronavirus Genome 2]].
#[[:Category:Old Days|Old Days]]
##A two comic series released with almost 3.5 years between the. When the first comic [[1755: Old Days]] was released in November 2016 it was not a series. That was first obvious when [[2324: Old Days 2]] was released in June 2020. The second comic continues the discussion of programming in the old days - directly from the first comic in spite of more than 3 years between them.
##Once again a series where the second comic just adds a "2" to the title. And once again one with long time between the first and the second comic, that made it a series.
#[[:Category:Alien Visitors|Alien Visitors]]
##A two comic series released over two consecutive but normal release day Wednesday and Friday. The first comic [[2477: Alien Visitors]] was released 2021-06-16. 
##It was first clear that this was going to be a series with the Friday release [[2478: Alien Visitors 2]] on 2021-06-18.
#[[:Category:Cursed Connectors|Cursed Connectors]]
##So far two comics have been released, but given the connectors have numbers 65 and 187 there could be many more to come.
##The first was released on July 23rd 2021, it was <nowiki>#187</nowiki>: [[2493: Dual USB-C]]. And it became a series with the second comic released just two comics later the next week on July 28th with <nowiki>#65</nowiki>: [[2495: Universal Seat Belt]].
##It is thus similar to the [[:Category:Bad Map Projections|Bad Map Projections]] series.

===Other series===
Here is a list of the (2 as of 2016) other types of series that has been used for explaining certain aspects of xkcd without being a series in any clear way on xkcd:
#[[:Category:A Smarter Planet|A Smarter Planet]]
##A two comic series from the summer of 2009 made specially for IBM's blog A Smarter Planet, and thus not part of the regular xkcd comics. Although the obviously have been made as a set, their stories are not related in any way, and their titles [[Conservation]] and [[Prescriptions]] are also not related. So they would only make a series because they were made for the same specific reason.
#[[:Category:Comics sharing name|Comics sharing name]]
##This category lists comics that share name with another comic, or almost shares name. So many series would be here. But there are also some series like comics that are not directly related in a series, like the new years comics released under the title of the new year. (2012, 2014 and 2016 so far). Many of the comics that share name or almost share name is not in any way part of the same series. The category is mainly used for explaining comics with similar name.

===Not series===
#[[:Category:COVID-19|COVID-19]] 
##This category contains the many comics from March 2020 and on that where inspired by the {{w|2019–20 coronavirus pandemic|2019-20 pandemic}} of the {{w|coronavirus}} {{w|SARS-CoV-2}} which results in the {{w|coronavirus disease 2019}}, COVID-19 for short.
##They are not seen as a comic series, as most of them has no direct relation to the story or subject of the others, except the overall relation to COVID-19.
##There can be exceptions within the category, as there now is a direct series relating to the [[:Category:Coronavirus Genome|Coronavirus Genome]].
