You can now find online a fairly complete bibliography of the Macrostomidae (including some papers on Microstomidae and the Dolichomacrostomidae). Most of the over 200 papers are also deposited as PDFs (for more detail see About the Bibliography).
I hope you will find this useful.
To just use the bibliography you do not need a user account. The information is accessible to everyone . But if you would like to contribute to the the bibliography (or to the Macrostomorpha site in general) please register for a user account. With your help we can have a more comprehensive bibliography soon.
