Many disciplines have one or more platforms where researchers can connect with colleagues, collaborate, and share scholarship. Some platforms are mostly used for sharing working papers, preprints, or published papers, while others have a stronger networking component.
For book chapters, journal articles, or any other type of work that you have previously published, make sure you have the right to share the work. If you have it, check your original publishing agreement. If not, check the journal website for the publisher's policy on author rights or sharing, or use one of the tools below.
