Even from this, it's unclear what the LGBT Staff Network thought the actual "risk of serious harm to staff and visitors" might be. Although the recognised trade union for the Library supported the Network and advocated to exclude the book from the exhibition because it involved "a very real issue of harm to staff and the risk of discrimination".
So, it's clear what angle they were coming from
However, the Investigator, after talking to various members of staff and the leadership team takes the position that the risk concerned demonstrations from trans-rights activists disrupting the exhibition.
So, nothing to do with the book itself, rather extremist reactions to the book from people on one side of the debate.
The report says of the National Librarian:
"She considered risks may include protests at the Library which would disrupt the exhibition and operations more widely, with potential for violence directed towards both staff and visitors, ... She told me that she had read the book, and was concerned about accounts of protests, sometimes including violence, witnessed by authors."
So, since there had been violent protests against women in the past then she didn't want any of that sort of thing going on in her library and the simplest thing was just not to display the book.
However, the Investigator later says:
"I do not accept the Librarian undertook an adequate or appropriate assessment of risk to inform her decision. ... I found no evidence she considered appropriate means of mitigating the risks she identified. She did not, for example, consult police to identify the likelihood of protests and disruption, or whether there were means of managing those events to mitigate the risk and keep staff and visitors safe."
The report goes into a lot more details in all the areas that the Library got wrong. This is from the final section of the report:
"What influencing factors may have contributed to the decision
From my review and in discussions with staff it was clear that there were several factors involved in the decision. This included a desire to avoid controversy which may overshadow the celebratory nature of the exhibition, as well as potential damage to relationships with stakeholders and supporters of the Library which might result. It was also based on what I think was a genuine concern about risk of harm to staff and visitors, albeit I have found that was not adequately explored.
However, in my view, the main determining factor in the decision was advocacy by the Network and allies, supported by the Library's recognised trade union. They identified the book as posing a serious risk of harm to staff and visitors. Their indications they would "go public" and raise the issue with external stakeholders was a significant and weighty factor which led directly to escalation of the book's inclusion to the LLT and was seriously considered throughout the decision-making process. It is unclear whether the Network is intended to be an internal advocacy body or a group for mutual support. Nonetheless, it played a central role in objecting to the book's inclusion and ultimately having it excluded from the exhibition."
