Indexing process


Conventional indexing

The indexer reads through the text, identifying indexable concepts (those for which the text provides useful information and which will be of relevance for the text's readership). The indexer creates index headings to represent those concepts, which are phrased such that they can be found when in alphabetical order (so, for example, one would write 'indexing process' rather than 'how to create an index'). These headings and their associated locators (indicators to position in the text) are entered into specialist

which handles the formatting of the index and facilitates the editing phase. The index is then edited to impose consistency throughout the index. Indexers must analyze the text to enable presentation of concepts and ideas in the index that may not be named within the text. The index is intended to help the reader, researcher, or information professional, rather than the author, find information, so the professional indexer must act as a liaison between the text and its ultimate user. In the United States, according to tradition, the index for a non-fiction book is the responsibility of the author, but most authors don't actually do it. Most indexing is done by freelancers hired by authors, publishers or an independent business which manages the production of a book, publishers or book packagers. Some publishers and database companies employ indexers. Before indexing software existed, indexes were created using slips of paper or, later,

Indexing software

Software is available to aid the indexer in building a book index. There are several dedicated indexing software programs available to assist with the special sorting and copying needs involved in index preparation.


Embedded indexing

Embedded indexing involves including the index headings in the midst of the text itself, but surrounded by codes so that they are not normally displayed. A usable index is then generated automatically from the embedded text using the position of the embedded headings to determine the locators. Thus, when the pagination is changed the index can be regenerated with the new locators.

), as well as other tools (for example, MadCap Software's Flare), have some facility for embedded indexing as well. TExtract and IndexExploit support embedded indexing of Microsoft Word documents. An embedded index requires more time to create than a conventional static index; however, an embedded index can save time in the long run when the material is updated or repaginated. This is because, with a static index, if even a few pages change, the entire index must be revised or recreated while, with an embedded index, only the pages that changed need updating or indexing.


Purpose

Indexes are also designed to help the reader find information quickly and easily. A complete and truly useful index is not simply a list of the words and phrases used in a publication (which is properly called a concordance), but an organized map of its contents, including
cross-referenceThe abbrevation Xref can refer also to External Reference The term cross-reference (abbreviation: xref) can refer to either: * An instance within a document which refers to related information elsewhere in the same document. In both printed and on ...

''See'' ''Salvia coccinea'' ← redirecting the reader to term used in the text :shade plants ← grouping term (may not appear in the text; may be generated by indexer) ::hosta, 93 ← subentries ::myrtle, 46 ::Solomon's :sunflower, 47 ← regular entry In books, indexes are usually placed near the end (this is commonly known as "BoB" or back-of-book indexing). They complement the

by enabling access to information by specific subject, whereas contents listings enable access through broad divisions of the text arranged in the order they occur. It has been remarked that, while " first glance the driest part of the book, on closer inspection the index may provide both interest and amusement from time to time."


Index quality

Some principles of good indexing include: * Ensuring each topic/section includes a variety of relevant index entries; use two or three entries per topic * Understanding the audience and understand what kind of index entries they're likely to look for * Use the same form throughout (singular vs. plural, capitalisation, etc.), using standard indexing conventions Indexing pitfalls: * Significant topics with no index entries at all * Indexing 'mere mentions': "But John Major was no Winston Churchill..." indexed under 'Churchill, Winston' * Circular cross-references: 'Felidae. ''See'' Cats'; 'Cats. ''See'' Felidae' * References to discussions of a single topic scattered among several main headings: 'Cats, 50–62'; 'Felidae, 175–183' * Inconsistently indexing similar topics * Confusing similar names: Henry V of England, Henri V of France * Incorrect alphabetization: 'α-Linolenic acid' under 'A' instead of 'L' * Inappropriate inversions: 'processors, word' for 'word processors' * Inappropriate subheadings: 'processors: food, 213–6; word, 33–7' * Computer indexing from section headings: e.g. 'Getting to know your printer' under 'G'
