This is a really useful overview of the LGBTQ+ movement which I think is primarily aimed at young people, but it's suitable for all ages if you're looking for an introduction. It's visually engaging with lots of colour and different formats and covers a comprehensive range of topics within the movement - from evidence of LGBTQ+ people in ancient history, to key legal milestones, to LGBTQ+ icons in a range of industries such as music, film and sport.
More importantly, it included useful definitions of language as this can be one of the biggest stumbling blocks when it comes to educating people who may be afraid of using the wrong word etc. The only criticism I have is from the page of pronouns. While it was useful to break down the subjective/objective/possessive (e.g. she, her, hers etc.), I felt that it was missing the link to the identities that they're commonly associated with - e.g. 'zir/hir' is one I was completely unfamiliar with, and I still wasn't clear who would use that, and what the difference is between zir and hir - and even how to pronounce it! A small criticism in what is otherwise a very good introduction to this topic.
