Archie is a tool for indexing FTP archives, allowing users to more easily identify specific files. It is considered the first Internet search engine. The original implementation was written in 1990 by Alan Emtage, then a postgraduate student at McGill University in Montreal, Canada. Archie was superseded by other, more sophisticated search engines, including Jughead and Veronica, which were search engines for the Gopher protocol. These were in turn superseded by search engines like Yahoo! in 1995 and Google in 1998. Work on Archie ceased in the late 1990s. A legacy Archie server was maintained for historic purposes in Poland at Interdisciplinary Centre for Mathematical and Computational Modelling in the University of Warsaw until 2023.
MEDLINE is a bibliographic database of life sciences and biomedical information.

The Entrez Global Query Cross-Database Search System is a federated search engine, or web portal that allows users to search many discrete health sciences databases at the National Center for Biotechnology Information (NCBI) website.

The name "Entrez" was chosen to reflect the spirit of welcoming the public to search the content available from the NLM.
Comic book collecting is a hobby that treats comic books and related items as collectibles or artwork to be sought after and preserved. Though considerably more recent than the collecting of postage stamps (philately) or books (bibliophilia), it has a major following around the world today and is partially responsible for the increased interest in comics after the temporary slump experienced during the 1980s.

A search engine is a software system that provides hyperlinks to web pages and other relevant information on the Web in response to a user's query. The user inputs a query within a web browser or a mobile app, and the search results are often a list of hyperlinks, accompanied by textual summaries and images. Users also have the option of limiting the search to a specific type of results, such as images, videos, or news.
A bibliographic database is a database of bibliographic records. This is an organised online collection of references to published written works like journal and newspaper articles, conference proceedings, reports, government and legal publications, patents and books. In contrast to library catalogue entries, a majority of the records in bibliographic databases describe articles and conference papers rather than complete monographs, and they generally contain very rich subject descriptions in the form of keywords, subject classification terms, or abstracts.
