Automatic indexing

Created Talk Page

Wow, this article is a mess. I don't know what else to do for it. I am very uninformed in this area.―Matthew J. Long -Talk-^☖ 19:49, 9 December 2017 (UTC)[reply]

It was not exactly a mess since there was very little info provided. :) I have expanded it in an effort to help this article graduate from being a stub. Please let me know if you have questions about the additional info and edits I made. Thanks! Darwin Naz (talk) 00:52, 11 October 2018 (UTC)[reply]

Hollerith tabulating machines were used for indexing

Before digital computer Hollerith punched card tabulating machines were used with inverted indexes.

Also other cards with holes along their four edges, where used for indexing. Each hole represent one attribute yes/no, The holes were cutted opened for attribute "yes" in a way that inserting a long needle through the holes one can separate the card set with the attribute "no" held with the needle and the rest with attribute "yes", with the hole opened, stay in the box. Indexing predates digital computers, as mentioned with the two examples mentioned. — Preceding unsigned comment added by 2806:106E:B:DB5C:31E1:43D1:9E0:2EF (talk) 03:44, 21 June 2023 (UTC)[reply]
