An etext is a text that has been typed into a computer file and is thus searchable. Tens of thousands of Sanskrit texts have now been keyed-in, and are available to download for free from the web. Once a sizable etext archive has been downloaded, or better yet, obtained all at once from a colleague, one can search the whole corpus using a program with multi-file search capabilities such as the free and powerful TextWrangler (on Mac OSX). Windows users might try the shareware WinGREP, while Linux has it built in. It is often enough just to type in your search word without the ending (because of sandhi variation), but more refined searches can be easily accomplished with a search language called GREP. For a helpful introduction on using GREP with Sanskrit etexts, see Somadeva Vasudeva’s brief exposition here. I would like to echo Dr. Vasudeva’s plea concerning making your own etexts: it is not very time consuming when you consider the amount of time it takes simply to read a Sanskrit text and if you share your texts then the whole community of Sanskrit scholars benefits.
I have published the following etexts:
➤ Kāśyapīya Garuḍapañcākṣarīkalpa
(based on the 1933 ed. of Yatirāja Sampatkumāramuni)
A detailed summary can now be found on my blog.
➤ Nārāyaṇīya Tantrasārasaṃgraha
(based on the 1950 ed. of M. Duraiswami Aiyangar)
I have also typed in the following, but have not made them publicly available for various reasons. I am willing to share these “in-progress” etexts for those with a special interest:
➤ Yogaratnāvalī of Śrīkaṇṭhapaṇḍita
➤ Śivatattvaratnākara 6.26–27
➤ Jāṅgulīvidyā (Śaiva)
➤ Indrajālavidyāsaṃgraha (beginning only)
➤ Siddhapañcāśikā (Kaula)
