________________________________________________________________The so-called gray literature is a recognized category of publication the world over but for a variety of reasons it is viewed as a substandard source of scholarly information. This literature facilitates multi-vocality in a profession that is split between those who dominate power roles, educational outlets, and publication venues and those who are in-thetrench practitioners who generate voluminous amounts of material. Taken less seriously by those who incorrectly suggest that reports are not peer reviewed or are inaccessible, these sources will be more widely cited if those outside the specific report-producing communities understand how to access them and understand their scholarly responsibility to do so. ________________________________________________________________Résumé: La littérature dite grise est une catégorie de publication reconnue dans le monde entier mais qui, pour diverses raisons, est considérée comme une source d'information spécialisée inférieure. Cette littérature facilite la multivocalité dans une profession qui est partagée entre ceux qui dominent les rô les du pouvoir, l'éducation et les lieux de publication, et les professionnels de terrain qui produisent de grandes quantités d'informations. Moins prises au sérieux par ceux qui suggèrent incorrectement que les rapports ne sont pas examinés par des pairs ou sont inaccessibles, ces sources d'information seront plus largement citées si ceux qui sont en dehors des milieux spécifiques de production des rapports savent comment les utiliser et comprennent leur responsabilité scientifique de le faire. ________________________________________________________________

________________________________________________________________The ''grey literature problem'' is a common phrase because technical reports produced by the majority of practitioners are perceived to be inaccessible, not peer-reviewed, and of low quality. These issues, however, are as much cultural as they are about indexing and databases, review procedures, and content. Unconventional, non-university-based publication venues and alternative forms of literature constitute an opportunity for bringing fresh ideas and new perspectives to the discipline, for reporting state-of-the-art research, and engaging a wider pool of participants. Nontraditional publication venues have a range of benefits including speedy distribution, presentation of abundant amounts of data, inclusion of in-depth analyses, consideration of a range of methodological and theoretical issues using sizable datasets, often rigorous multi-tiered peer review, and avoidance of many of the stifling political hurdles and time delays of traditional publishing. Honest pursuit of knowledge and effective communication begin with citation of this alternative form of publication, objective assessment of its content absent a double standard, and acknowledgement of the scholars who produce it.

New methodologies are needed to address multiple componentcy and short reuse episodes that are characteristic of mobile group residential and logistical strategies. Chronometric results are often misinterpreted when evaluated within a framework suited to long-term sedentary occupations. The standard practices of age-averaging, eliminating apparent "anomalous" results, and relying on high profile diagnostic tools and vessels and the most visible features—along with the expectation for "contextual congruence"—mask multi-componentcy and episodic reuse. High incidences of site reuse have been detected by considering alternate site development models and looking specifically for evidence of distinct shorter term occupations.

Highly mobile people must have sheltered in structures of some kind; but these are notoriously difficult to find. The author uses nineteenth-century photographs of an occupied Apache settlement to show how such shelters may have been made, comparing them with their archaeological remains in the present day. This suggests a 'signature' for the temporary shelters used by mobile groups in any period.
