The National Academies Press publication "On Being a Scientist: A guide to responsible conduct in research. Third Edition. 2009 is a great resource to understand scientific integrity, authorship guidelines, treatment of data and negligence. Free downloads or online reading can be found here: https://nap.nationalacademies.org/read/12192/chapter/1
Authorship guidelines can be found in each journal. Most journals have adopted CRediT, the Contributor Role Taxonomy. Additionally, the NIH intramural program has a guide to authorship and conflict of resolution on authorship:

We support these guidelines and understand that authorship should be discussed collegially throughout the publication process and that the PI's and project leaders for each project will discuss authorship and authorship order with all authors.Â
Another useful resource for guildelines on defining the roles of authors is provided by the ICMJE (International Committee of Medical Journal Editors):
