Essentially, when responding to a question with reference to the scriptures, I tend to base it on memory, then use Google to find a reference source. However, in the interest of providing as reliable sources as possible, I wonder if there are "search engine(s)" or other sources that people generally search, to refer to in answers.
Main sources used by answers on the site seems to be:
What do you use as a reference source? Your own memory, from having studied the scripture, or do you look it up in a search engine?
(Wasn't sure if this was a question for the main site, regarding what sources are online, and another for this Meta, regarding accuracy of sources/quotes, please suggest revisions for clarification)
(On a side note, I am working with a monastery to build a cross-reference database for teachings - multimedia files - and am looking for reliable sources with taxonomies and synonyms that can be referenced from there as well)
