The '''Internet Speculative Fiction Database''' ('''ISFDB''') is a database of bibliographic information on genres considered [[speculative fiction]], including [[science fiction]] and related genres such as [[fantasy fiction|fantasy]], [[alternate history]], and [[horror fiction]]. The ISFDB is a volunteer effort, with the database being open for moderated editing and user contributions, and a wiki that allows the database editors to coordinate with each other. {{As of|2025|6|post=,}} the site had catalogued 2,380,108 story titles from 283,651 authors.

The code for the site has been used in books and tutorials as examples of database schema and organizing content. The ISFDB database and code are available under [[Creative Commons license|Creative Commons licensing]]. The site won the Wooden Rocket Award in the Best Directory Site category in 2005.

== Purpose ==
The ISFDB database indexes [[speculative fiction]] ([[science fiction]], [[fantasy fiction|fantasy]], [[horror fiction|horror]], and [[alternate history]]) authors, novels, short fiction, essays, publishers, awards, and magazines in print, electronic, and audio formats.<ref name="sfsite"/><ref name="craphound"/> It supports author pseudonyms, series, and cover art plus interior illustration credits, which are combined into integrated author, artist, and publisher bibliographies with brief biographical data. An ongoing effort is verification of publication contents and secondary bibliographic sources against the database, with the goals being data accuracy and to improve the coverage of speculative fiction to 100 percent.

== History ==
Several speculative fiction author bibliographies were posted to the [[USENET]] [[newsgroup]] rec.arts.sf.written from 1984 to 1994 by Jerry Boyajian, Gregory J. E. Rawlins and John Wenn. A more or less standard bibliographic format was developed for these postings.<ref name="onpedia"/> Many of these bibliographies can still be found at The Linköping Science Fiction Archive.<ref name="linkoping sffa"/> In 1993, a searchable database of awards information was developed by Al von Ruff.<ref name="onpedia" /> In 1994, John R. R. Leavitt created the Speculative Fiction Clearing House (SFCH). In late 1994, he asked for help in displaying awards information, and von Ruff offered his database tools. Leavitt declined, because he wanted code that could interact with other aspects of the site. In 1995, Al von Ruff and "Ahasuerus" (a prolific contributor to rec.arts.sf.written) started to construct the ISFDB, based on experience with the SFCH and the bibliographic format finalized by John Wenn. The first version of ISFDB went live on 8 September 1995, and a URL was published in January 1996.<ref name="onpedia" /><ref name="isfdb whats new 1995"/><ref name="isfdb whats new 1996"/>

The ISFDB was first located at an ISP in Champaign Illinois, but it suffered from constrained resources in disk space and database support, which limited its growth.<ref name="onpedia" /> In October 1997 the ISFDB moved to [[SF Site]], a major SF portal and review site.<ref name="craphound" /><ref name="onpedia" /> Due to the rising costs of remaining with SF Site, the ISFDB moved to its own domain in December 2002, but it was shut down by the hosting ISP due to high resource usage.<ref name="sfwa news 20030405"/><ref>{{Cite web |title=What's New from 2003 - ISFDB (Jan)|url=https://isfdb.org/wiki/index.php/What%27s_New_from_2003#What.27s_New_-_18_January_2003 |access-date=2023-01-14 |website=isfdb.org}}</ref> In February 2003, it began to be hosted by The Cushing Library Science Fiction and Fantasy Research Collection and Institute for Scientific Computation at [[Texas A&M University]].<ref name="sfwa news 20030405" /><ref>{{Cite web |title=What's New from 2003 - ISFDB (Feb)|url=https://isfdb.org/wiki/index.php/What%27s_New_from_2003#What.27s_New_-_11_February_2003 |access-date=2023-01-14 |website=isfdb.org}}</ref> The ISFDB moved to a commercial hosting service in 2008.<ref>{{Cite web |title=What's New from 2008 - ISFDB |url=https://isfdb.org/wiki/index.php/What%27s_New_from_2008#What.27s_New_-_12_April_2008 |access-date=2023-01-14 |website=isfdb.org}}</ref>

On 27 February 2005, the database and the underlying code became available under [[Creative Commons license|Creative Commons licensing]].<ref name="onpedia" /><ref name="isfdb lic"/><ref name="isfdb whats new 2005"/>

ISFDB was originally edited by a limited number of people, principally Al von Ruff and Ahasuerus.<ref name="isfdb major contributors"/><ref name="isfdb top contributors"/> Editing was opened in 2006 to the general public on an open content basis, with changed content being approved by one of a limited number of moderators in an attempt to protect the accuracy of the database.<ref name="other worlds 20061223"/>

In late 2022, the ISFDB faced public criticism for refusing to update its entry for the [[transgender]] author Lee Mandelo to reflect his new name. The update was finally made after more than a year of repeated requests.<ref name="sanford 20221231"/>

==Awards and reception==
In 1998, [[Cory Doctorow]] wrote in ''Science Fiction Age'' that "[T]he best all-round guide to things science-fictional remains the Internet Speculative Fiction Database".<ref name="craphound" /> In April 2009, Zenkat wrote that "it is widely considered one of the most authoritative sources about Science Fiction, Fantasy, and Horror literature available on the Internet".<ref name="freebase 20090419"/> ISFDB was the winner of the 2005 Wooden Rocket Award in the ''Best Directory Site'' category.<ref name="sf crowsnets 2005 wooden rocket"/>

Ken Irwin reviewed the site for ''[[Reference Reviews]]'' in 2006, praising "the scalable level of detail available for particular authors and titles" while also pointing out "usability improvements" needed at that time. He concludes by calling it "a tremendous asset to researchers and fans of speculative fiction", stating that no other online bibliographies have "the breadth, depth, and sophistication of this database".<ref name="irvin ref rvw 2006">{{cite journal |last1=Irwin |first1=Ken |date=October 2006 |editor1-last=Chalcraft |editor1-first=Tony |title=Internet Speculative Fiction Database (ISFDB) |url=https://www.proquest.com/docview/862159187 |journal=[[Reference Reviews]] |publisher=[[Emerald Group Publishing]] |volume=20 |issue=7 |pages=30–32 |doi=10.1108/09504120610691619 |url-access=limited |issn=0950-4125 |access-date=July 14, 2022 |id={{ProQuest|862159187}} }}</ref> On [[Tor.com]], James Davis Nicoll described the site as "the single best [SFF] bibliographical resource there is".<ref name="tor nicoll review">{{cite web |url=https://www.tor.com/2021/04/30/the-single-best-bibliographical-resource-there-is-if-you-like-sff/ |title=The Single Best Bibliographical Resource There Is (if You Like SFF) |first=James Davis |last=Nicoll |date=April 30, 2021 |publisher=[[Tor.com]] |access-date=July 14, 2022 |archive-date=July 14, 2022 |archive-url=https://archive.today/20220714211217/https://www.tor.com/2021/04/30/the-single-best-bibliographical-resource-there-is-if-you-like-sff/ |url-status=live }}</ref> Gabriel McKee, author of ''The Gospel According to Science Fiction'', described the site as an "indispensable [source] of information in putting this project together",<ref name="mckee gospel 2007">{{cite book |title=The Gospel According to Science Fiction: From The Twilight Zone to the Final Frontier |first=Gabriel |last=McKee |date=January 2007 |publisher=[[Westminster John Knox Press]] |page=ix |isbn=978-0-664-22901-6 }}</ref> and the site was described as "invaluable" by [[Andrew Milner]] and J.

As a real-world example of a non-trivial database, the [[Database schema|schema]] and [[MySQL]] files from ISFDB have been used in a number of tutorials. Schema and data from the site were used throughout Chapter 9 of the book ''Rails for Java Developers''.<ref name="halloway gehtland 2007"/> It was also used in a series of tutorials by [[Lucid Imagination]] on [[Solr]], an enterprise search platform.<ref name="solr isfdb"/>

{{As of|2013|9}}, [[Quantcast]] estimates that ISFDB is visited by over 67,400 people monthly.<ref name="quantcast 20130927"/> The database, {{As of|lc=yes|2025|6|1}}, contains 2,380,108 unique story titles from 283,651 authors.<ref name="stats"/>
