### 1.3. Where can I find out more? 

**+++UPD**

The ultimate source (not counting for software code itself) is InChI Technical Manual which is available from InChI Trust downloads page, see item **3.6** below.

For a briefer and less technical description, look at: *Heller, S., McNaught, A., Pletnev, I., Stein, S., and Tchekhovskoi, D. InChI, the IUPAC international chemical identifier. Journal of Cheminformatics 7 (2015), 23–23*. DOI: [10.1186/s13321-015-0068-4](http://dx.doi.org/10.1186/s13321-015-0068-4)

For much more brief description, as well as background and history, look at*: Heller, S., McNaught, A., Stein, S., Tchekhovskoi, D., and Pletnev, I. InChI - the worldwide chemical structure identifier standard. Journal of Cheminformatics 5 (2013), 7–7*. DOI: [10.1186/1758-2946-5-7](http://dx.doi.org/10.1186/1758-2946-5-7)
