There are many questions asking for lecture notes on some topic. And about a week ago also the tag lecture-notes has been created. The question is to which extent this tag can be useful and whether it should be kept or removed. (In any case, since the new tag can affect many question, I think it is good to discuss it on meta before taking any further actions.)
- Currently there are 3 questions having that tag. In two cases the tag was added by the tag-creator. In the third case I do not think the tag fits: Spoof lecture for beginning first year undergraduates.
- As far as I can say, the questions of this type have been so far usually tagged reference-request or, more specifically, reference-request+online-resources.
- The situation is somewhat similar to discussion about separate tag for videos, where the conclusion was to use online-resources. However, the difference is that we have more often questions about lecture notes than questions about videos.
- Another similar tag is book-recommendation. Creation of this tag has been discussed here: Do we need a tag for Books?
- I can easily imagine question which ask both for books and lecture notes. Such question would be tagged reference-request, book-recommendation, lecture-notes and possibly also online-resources. Considering that a question can only have 5 tags, this would already take large part of available slots without saying anything about the mathematical classification of the topic.
- If the tag is kept, it should be added at least to some most prominent past questions asking for lecture notes - so that this new tag is actually useful for searching.
- And if the tag stays, it would be good to created also some tag-info containing the guidance of the usage of this tag.
